What are the best practices for error handling in Node.js?

In Node.js, it's important to handle errors gracefully. Some best practices include using try-catch blocks, handling promise rejections, and logging errors for debugging.

Can you explain how to use try-catch blocks effectively?

Sure! Try-catch blocks allow you to catch synchronous errors. You wrap your code in a try block and handle any errors in the catch block.

What about handling asynchronous errors?

For asynchronous code, you can use .catch() with promises or try-catch with async/await. Always ensure to handle rejections.

How can I log errors for better debugging?

You can use logging libraries like Winston or Bunyan to log errors. They provide features like log levels and transports for better management.
